If you like, you could look on the C3 as a Cisco Hybrid (CatOS + IOS). You do not require a relay agent in the router interface. You configure a pool for each address range you need to serve and the 'pool network' command defines the addresses that each pool will serve.
The 'set IP address' command can be a tough concept to grasp. However, unlike the E1 for example, the IP address on the switch cannot be in a subnet that is on the router (NB this may change). What this means in practice is that, if the C3 is your only router then you manage the C3 by telnet to one of the router interfaces and don't bother with the "set IP address' command. You will need to set an IP address on the B3s in order to manage them, of course.

Yes I was aware that the router was a C3! Setup principles are similar to Cisco and I have also set up C3s as routers, though not routing between VLANs in trunks. VLANs are router interfaces. You simply attach the required router interface to the vlan using 'interface vlan nnn' . As long as the VLAN is up (something connected to it), then the router interface is up. I see that others have replied but haven't read their answers in detail. Just give a shout if you need more help. We can even set up a lab here and test it, though may not manage that till next week.

I would suggest something like this (assuming you have cleared configs on the switches just in case something in the old config conflicts with the new): L2 switch as follows: set vlan create 2 set vlan create 3 set vlan egress 2 ge.1.1 tagged set vlan egress 3 ge.1.1 tagged (you must tag the VLAN on transmit (egress) else the other end won't know which packet belongs to which VLAN when it receives it!!) L3 switch: set vlan create 2 set vlan create 3 set vlan egress 2 ge.1.1 tagged set vlan egress 3 ge.1.1 tagged (this mirrors the L2 switch VLAN and port config) To verify that your VLANs are OK across the trunk, try attaching PCs to some test ports (one in each VLAN on each switch) and pinging between the switches. Test port: Set port vlan ge.1.2 2 modify-egress (i.e. untagged) Set port vlan ge.1.3 3 modify-egress Do this on each switch. If ping doesn't work, check MAC-tables e.g. show mac fid 2 and look for LEARNED MAC addresses. If all is well, then you can try the router config. In the router config you must assign IP-addresses to these VLANs and remember 'no shutdown'. As I recall, the VLAN must be UP in order for the router interface to work!

Hi, You don't need to define a port as trunk port, you only have to put the port in the egress table for the vlans you need. For example, set vlan create 2 set vlan create 3 set vlan egress 2 ge.1.1 set vlan egress 3 ge.1.1 With this configuration you are sending frames from vlans 2 and 3 through this port. You can check it using "show port egress ge.1.1" You can implement more options, but this is the basic configuration.
